XE2 has a more recent sensor than the X Pro 1 (which has same as XE1.) X Pro 1 has the hybrid optical viewfinder, and it's overall larger in the hand (more so than the specs might indicate, IMHO.)
Some very good lenses, though not a wide selection. I have the 14, 35, and the 18-55 and 55-200 zooms. All are very good to excellent. Love the 14 and the 35, and the 55-200, and I like the 18-55. The new 23 is supposed to be terrific, and I'm hopeful that the upcoming 56 will be as well. The 60 macro is also excellent, though I chose the 18-55 instead and sometimes regret that.
I have a couple of XE1 bodies, and they've been a lot of fun -- and a lot of time learning how to handle their quirks.
